The upcoming virDomainBackup() API needs to take advantage of various

Add two capabilities for testing features required for the upcoming
virDomainBackupBegin: use block-dirty-bitmap-merge as the generic
witness of bitmap support needed for checkpoints (since all of the
bitmap management functionalities were finalized in the same qemu 4.0
release), and the bitmap parameter to nbd-server-add for pull-mode
backup support. Even though both capabilities are likely to be
present or absent together (that is, it is unlikely to encounter a
qemu that backports only one of the two), it still makes sense to keep
two capabilities as the two uses are orthogonal (full backups don't
require checkpoints, push mode backups don't require NBD bitmap
support, and checkpoints can be used for more than just incremental
backups).
Existing code is not affected by the new capabilities.

Migration always uses a TCP socket for NBD servers, because we don't
support same-host migration. But upcoming pull-mode incremental backup
needs to also support a Unix socket, for retrieving the backup from
the same host. Support this by plumbing virStorageNetHostDef through
the monitor calls, since that is a nice reusable struct that can track
both TCP and Unix sockets.

The DO_TEST() macro in qemumonitorjsontest.c was not passing the
schema through, which meant that we were not validating any of those
tests for correct usage according to the schema.
In the process of mechanically altering tests to pass the schema
through, use VIR_AUTOPTR on all of the affected test instances. The
next patch will do some further cleanups that it exposes.
Tested by using this hack, where the test mistakenly passed pre-patch,

This configuration can be used by gitdm to generate reports about
libvirt development.
The goal I was working with was being able to generate a report
for every single libvirt release and having zero "email address
as company" entries; picking different commit ranges might result
in some contributions not being accounted for.
I had to make some judgement calls when the situation was not
entirely clear-cut: when in doubt, and not finding any obvious
signs of the opposite being true, I mostly ended up dumping
people in the "unaffiliated contributions" bin. If I got it
wrong, and companies want to get recognition for their sponsored
contributions to libvirt, they can send patches.

Ever since the feature was introduced with commit 0f8e7ae33a,
it has contained a logic error in that it attempted to use a NUMA
node map where a CPU map was expected.
Because of that, guests using <numatune> might fail to start:
# virsh start guest
error: Failed to start domain guest
error: cannot set CPU affinity on process 40055: Invalid argument
This was particularly easy to trigger on POWER 8 machines, where
secondary threads always show up as offline in the host: having
<numatune>
<memory mode='strict' placement='static' nodeset='1'/>
</numatune>
in the guest configuration, for example, would result in libvirt
trying to set the process affinity so that it would prefer
running on CPU 1, but since that's a secondary thread and thus
shows up as offline, the operation would fail, and so would
starting the guest.
Use the newly introduced virNumaNodesetToCPUset() to convert the
NUMA node map to a CPU map, which in the example above would be
48,56,64,72,80,88 - a valid input for virProcessSetAffinity().
